IMPROVEMENT IN TYPE-WRITERS.

i Specification forming part of Letters Patent No. 182,289, datedSeptember 19,1876; application filed May 27, 1876.

To all whom it may conce-ru:

Be it known that I, SAMUEL T. RYDER, of Plymouth, county of Plymouth andStateof Massachusetts, have invented a new and useful improvement inthat class of'instruments 'known as type-Writers, and which isespecially applicable to the so-called Sholes & Glidden Type-Writer,77which improvement is fullyset forth in the following specilication,reference being had to the accompanying drawin Tn the use ot' the'Sholes 8v Glidden type writer a serious inconvenience is realized inadjusting the paper to be printed to the cylindrical tympan withsufficient accuracy to enable a letter t0 be struck on a point preciselywhere it may be needed, or aline to be print;

ed in any nicely-definite directionwhich may be required, the gaging orother available devices designed i'or those purposes on those machinesbeing imperfect and inadequate t0 the direct and convenientaccomplishment ot' these desirablefends. Y

` To obviate these inconveniences I have'invented a device which Idenominate an improved l'ine-register and letter-locater, and which willindicate with milch greater ease andaccuraey a point 'for a letter and adirection for a line-t0 `be printed than any device nonT in use. Thismay be more fully shown by reference to the accompanying drawing. l

Figure l-A is ,the top plate ot' a Sholes 85 Glidden type-writer. B isthe cylindrical tympan, supported by the frame G C, and is movablevertically on the hinges a a, and laterally on the rod b b. The improvedlineregister and letter-locater consists of the indexes D N .on theplateis to imprint its mark N on the tympan. The frame E Eturns upon thehinges g y, and lies upon theplate A, as indicated by the dotted line ee, While operating` the machine for the purpose ot' type-writing- It isevident that the frame E E maybe detached, and the ends now hinged beinserted into Aholes at g g in Plate A, or at'other places, by which theindexes may be adjusted to the tympan in the same place, and serve theidentical purpose.

I claim'as my inventionl. The indexes D N D, supported upon the frame EE, in combination, by hingesg 9,With the plate A, as described.

2. The indexes D N D, hinged to the topplate of a type-writing machine,and arranged to indicate the printing-point and direction ot'printed'line, in combination with thenhinged tympan B, substantially asand for the purpose set forth.
